Detailed Description
walk a document tree and perform boolean opration on primitives.For each object fitting the group and mask, and is at the same child level, can be merged with other objects at that same level. Only if the object can be converted to polygons, this will be the case. For new polygons created this way, the BIN2 flags is set, so one is able to find them. The reuslting polygons are added to the target layer.

Member Function Documentation
| void a2dBooleanWalkerHandler::SetLinkHoles | ( | bool | doLinkHoles | ) | [inline] |
If set false a2dSurfaces will be produced, meaning holes stored seperately If true, the result will be a2dPolygonL objects, with holes linked in to outer contour. Only if operation is Boolean_Polygon2Surface, linked holes is ignored, and holes are not linked.
Definition at line 79 of file booloper.h.
| void a2dBooleanWalkerHandler::SetResultStroke | ( | const a2dStroke & | resultStroke | ) | [inline] |
Set the Result stroke style.
When set ( non wxNullStroke ), the style will be used for polygons resulting from a boolean operation.
Definition at line 93 of file booloper.h.
| void a2dBooleanWalkerHandler::SetResultFill | ( | const a2dFill & | resultFill | ) | [inline] |
Set the Result fill style.
When set ( non wxNullFill ), the style will be used for polygons resulting from a boolean operation.
Definition at line 100 of file booloper.h.
| void a2dBooleanWalkerHandler::SetStyleOfFirstChild | ( | bool | useStyle | ) | [inline] |
when set the style of the resulting polygons
will be the same as the first child (being part of the operation) found in a parent object. Unless m_resultStroke or m_resultFill or set.
Definition at line 107 of file booloper.h.
| bool a2dBooleanWalkerHandler::Start | ( | a2dCanvasObject * | object | ) | [virtual] |
called for boolean operation
All child objects of this parent and below, will be converted to polygons, and next a boolean operation will be applied.
Reimplemented from a2dWalker_LayerGroup.
